Description
:

Medium power 1550nm Watt Pilot is continuously variable attenuators based on polarization control of linearly polarized laser beams. Medium power 1550nm Watt Pilot consists of 2 high-performance polarizing optics components placed in precision opto-mechanical holder 5APH79T-1. Variable attenuator/beamsplitter incorporates a high-performance polarizing cube beamsplitter which reflects s-polarized light 90 while transmitting p-polarized light. A rotating quartz Phase λ/2 Waveplate is placed in the incident polarized laser beam. The intensity ratio of those two beams may be continuously varied without alteration of other beam parameters by rotating the waveplate. Ratio can be controlled over a wide dynamic range. Pure p-polarization could be selected for maximum transmission, or pure s-polarization for maximum attenuation of the transmitted beam.

Each Watt Pilot variable attenuator device is supplied in two different versions, manual or motorized. The intensity of the laser beam can be controlled over a wide dynamic range by rotating the waveplate. This can be done by hand in manual Watt Pilot devices or via special software in motorized Watt Pilot devices.
